CONVERTIBLE VAPOR-LAMP.

To all whom it may concern:

Be it known that I, LIBERTY K. FLANA-' can, citizen of the United States. residing at Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Convertible Vapor-Lamps, of which the following is a specification.

My invention relates to that class of lamps in which gasolene or other like fuel is forced to the burners of the lamp by compressed air, and before its delivery to the burners is converted into vapor.

The primary object of my invention is to provide a lamp of this type of a very simple and effective character which is convertible either into a standing lamp supported on a base, which base preferably forms the reser voir whereby fuel is supplied to the lamp, or into a hanging lamp adapted to be supported from the ceiling and securing its supply of fuel from an outside source.

A further object is to provide a lamp of this character in which a tubular generating chamber is used, which forms also the standard of the lamp and which contains wire gauze or like material, the tubular standard or generator being formed in two sections connected by a union so that the sections may be taken apart to permit the gauze to be removed, cleaned and replaced.

A further object is to provide a lamp with a vapor dome in which the vapor coming from the generator and mixed with air is stored, this dome forming a dead vapor chamber which kills the noise ordinarily incident to lamps of this type.

Other objects will appear in the course of the following description.

My. invention is shown in the accompanying drawings wherein:

Figure 1 is a vertical section of my lamp as mounted upon a standard. Fig. 2 is a fragmentary section taken at right angles to Fig. 1. Fig. 3 is a transverse section enlarged on the line 33 of Fig. 1. Fig. 1 is a side elevation of my lamp converted into a suspended lamp.

Referring to these drawings, Figs. 1 to- 3 show my lamp in the form in which it is supported upon a base or standard adapted. to be moved about and rested upon a table. In this form of my invention 2 designates the reservoir. Extending upward from the reservoir 2 is the tubular standard or genera- Specification of Letters Patent.

tor 5 which is provided wit-h the needle valve 6 by which the flow of oil up the tubular standard 5 may be controlled or checked. The tubular standard is preferably made in two parts or sections 5 and 5 connected by a union or coupling 7. The standard which is a relatively small tube is preferably surrounded by a removable sleeve 8, which in turn is surrounded by a removable cylin-' drical casing 9 held to the sleeve 8 by a set screw 10 or in any other suitable manner. The lower end of the sleeve 8 is provided with the outwardly flaring socket 11 in which the lower end of the casing 9 seats. The upper end of said casing supports a cap 12 having an internal tube 13 which fits over the tube 8 and is rotatable thereon. The upper end of the section 5 of the tubular standard 5 is screw threaded and is formed with a cap 14 provided with a very small opening 15. The interior of the tubular sections 5 and 5 is to be filled with wire gauze or asbestos designated by the numeral 16, this filling acting as a wick and drawing the gasolene upward where it can be easily discharged in the form of vapor through the perforation 15. The upper screw threaded end of the section 5 extends into a union coupling 17 whose lateral branches are connected to outwardly extend-- opens into a vapor dome 20. Extending.

downward from-the vapor dome on each side of the transverse air pipe 18 are the burner pipes 21, both precisely alike and carrying at their lower ends perforated terminals 22 supporting mantles 23. Mounted upon the extremities of the transversely extending air pipes 18 is the cylindrical, slightly tapering shield 241 which extends upward to a point above the lower edge of the :hamber 20, the upper portion of this shield 24 being spaced from the periphery of the chamber 20 so that air may pass up ward around the chamber 20, and so out of the burner. The upper end of the dome 20 is preferably conical in form and provided with the upwardly extending screw threaded nipple 25. Mounted upon the nipple 25 is the shade support 26 of any suitable character and supporting the downwardly depending shade 27 of any suitable or usual construction. In order to additionally support the shield, the dome and the burners upon the tubular standard 5, the transverse air pipes 18 are provided with downwardly extending supports 28 which converge toward each other, and are formed with a ring 29 which fits snugly around the projecting end of the internal tube 8, to which it is attached by a set screw or in any other suitable manner. The operation of this form of my invention will be obvious. The reservoir 2 is to be filled with gasolene or other liquid fuel and air is to be pumped into the reservoir to create sufficient pressure to force liquid fuel upward through the tubular standard, the passage of the liquid bein controlled by the valve 6. The liquid fuel is drawn upward through the tubular standard and is atomized Where it is forced through the perforation 15 in the cap 14. At this point it takes up air entering through the transversely extending air pipes 18 and the vapor is carried upward into the dome 20 which forms a dead air; space and superheats the hydrocarbon vapor. The gas passes downward through the burner pipes 21 and is ignited at the lower ends thereof, rendering the mantles incandescent.

In Fig. 1 I show my form of lamp as adapted to be suspended from the ceiling and to be fed from a reseroir not formed with the lamp but located at a distance therefrom. In this figure 30 designates a tubular support adapted to be attached to a ceiling and depending therefrom, and formed at its lower end with a screw threaded coupling 31 whereby it may be attached to the nipple 25 extending upward from the apex of the retort 20. A relatively small pipe preferably of copper and designated 32 extends down through the tubular support 30 and out at the lower end thereof. The other end of the supply pipe 32 extends to a reservoir or container 33 connected to an air pump 34 of any suitable character, whereby the fuel within the container 33 may be placed under pressure so that the fuel will be delivered through the pipe 32 to the lamp. The lamp portion comprising the tubular standards 5 and 5, the air pipes 18, the hood 24:, the conducting pipe 19, the dome 20 and the burner pipes 21, are all precisely as heretofore described. For the pur pose of regulating the flow of fuel to the burners, however, I attach a valve casing 35 to the lower end of the tubular standard 5, this valve casing having a valve seat 36 with which cooperates a needlevalve 37 which enters through the lower portion of the valve casing and extends vertically upward. The side of the valve casing 35 is formed with an opening provided with a gland 38 to which is connected a screw threaded coupling 39, which connects the copper pipe 32 to the valve casing. The pipe section 32 is of the same character as the pipe section 32, but in order that my lamp may be convertible from a standard lamp to a suspended lamp, I provide this feed pipe in two sections 32 and 32' connected by a coupling 40. Thus the pipe sections 32 and 32 may be disconnected from each other, the valve casing 35 disconnected from the pipe section 5, and the lamp very easily converted into a standard lamp by disengaging it from the tubular support 30 and engaging 'itwith the reservoir base 2. The interior of the feed pipe which performs the same functions as previously described, namely, that of a tubular vapor generator, is intended to be filled with wire gauze, asbestos or other suitable wicking 16 as before described.

The operation of the second form of my invention is precisely the same as that before described, with the difference that the fuel is forced into the lamp from the reservoir 33, instead of being forced into the lamp from the reservoir 2. It will be seen that I have provided means whereby my lamp may be converted in a comparatively short time and without skilled labor, from a standard lamp to a suspended lamp, and vice versa, without in any manner altering the construction of the lamp itself nor the operation of its various parts.

One of the particular advantages of my invention resides in the fact that the tubular generator being made in two sections may be readily disconnected so as to permit the packing of gauze or asbestos to be easily removed, cleaned and replaced whenever desired.

Another advantage is incident to the use of the vapor dome 20 which constitutes a dead vapor chamber which eliminates the noise usually incident to this form of lamp. Furthermore, it willcbe seen that this chamber 20 constitutes a superheater whereby the mixed air and gasolene vapor passing up the tube 19 is superheated and brought into proper condition for combustion.

I'Vhat I claim is:

1. A lamp comprising a standard having a fuel passageway therethrough, a four-way coupling mounted at the upper end of the standard, horizontally disposed air pipes connected with the opposite sides of the coupling, a feed pipe connected with the top of the coupling, a vapor dome mounted at the upper end of the feed pipe, burner pipes depending from the vapor dome at the opposite sides of said coupling, said burner pipes being provided at their lower ends with outlet openings, mantles surrounding the burner pipes and located above the outlet openings thereof, a shield supported upon the air pipes and surrounding the upper portions of the mantles and the lower portion of the vapor dome and spaced therefrom, a shade support mounted at the top of the vapor dome, and a shade carried by said support and surrounding the shield and having its lower edge portion projecting below the lower edge of the shield.

2. A lamp comprising a standard having a fuel passageway therethrough, a four-way coupling mounted at the upper end of the standard, horizontally disposed air pipes connected with the opposite sides of the coupling, a vertically disposed feed pipe connected with the top of the coupling, a dome mounted at the upper end of the feed pipe, burner pipes depending from said dome and extending along the opposite sides of the coupling and provided at their lower ends with outlet openings, mantles mounted upon the burner pipes above the outlet openings thereof, a shield mounted upon the air pipes and surrounding the upper portions of the mantles and the lower portion of the dome and spaced from the same, supports attached at their ends to the air pipes and connected at their lower ends with a ring, means for fixing the said ring to the standard, a support carried at the top of the dome, and a shade carried by said support and surrounding the shield and having its lower edge portions projecting below the lower edge of the shield.

In testimony whereof, I afiix my signature in presence of two witnesses.
